   Als endloses Material, das mit den in den Zustand eines Schaumes gebrachten wässerigen Dispersionen behandelt werden kann, kommt z. B. bahnförmiges oder anderes biegsames Material, eine Mehrzahl von parallelen Cordfäden, Bahnen von kardierte Baumwollflor oder kardierten Wollfloren, verfilzte Materialien, verschiedene Arten von Papier, in geleimtem oder ungeleimtem Zustand, auch solche, die aus mehreren Lagen aufgebaut sind, wie beispielsweise Teppiche u. dgl., in Betracht. 



   Ausführungsbeispiele : a) Zwei kardierte Baumwollflore mit einem Gewicht   von 17gpro Meter   (300 grains pro yard) werden in die Klemmstelle eines mit einem Koagulationsmittel versehenen Walzenpaares eingeführt. Ein Schaum wird durch Schlagen einer Mischung von der Zusammensetzung :

Dieser Schaum wird in der Klemmstelle zwischen den beiden Floren   angehäuft   und das vereinigte Material tritt an der andern Seite der Klemmstelle in Form einer kardierten Baumwolle, die durch ein poröses Koagulum verkittet und von diesem durchdrungen ist, aus. b) Ein ähnlicher Schaum, wie der in Beispiel a beschriebene, wird in die Klemmstelle eines mit einem Koagulationsmittel versehenen Walzenpaares auf einer Seite einer Gewebebahn, z. B. einem Gewebe aus Indiana, eingeführt. Das sich ergebende Erzeugnis besteht aus dem Indiana-Gewebe, welches auf einer Seite mit einer dünnen Schichte aus porösem Kautschuk   überzogen   ist. 



   In beiden Fällen war das verwendete Koagulationsmittel eine 10% ige wässerige Essigsäure ; die Vulkanisation kann in bekannter Weise nach   dem Trocknen durchgeführt   werden. 



   Die Dispersionen, welche gemäss der Erfindung in dem Zustand eines   Schaumes   Anwendung finden, umfassen solche, die aus Kautschuk,   Guttapercha,   Balata oder ähnlichen   natürlichen   oder   künstlichen   Pflanzenstoffen in vulkanisiertem oder in nicht vulkanisiertem Zustande bestehen oder

   As an endless material which can be treated with the aqueous dispersions brought into the state of a foam, e.g. B. web-shaped or other flexible material, a plurality of parallel cords, webs of carded cotton pile or carded wool pile, felted materials, different types of paper, in the glued or unsized state, including those made up of several layers, such as carpets and the like . Like., into consideration.



   Embodiments: a) Two carded cotton webs weighing 17 g per meter (300 grains per yard) are inserted into the nip of a pair of rollers provided with a coagulant. A foam is made by whipping a mixture of the composition:

This foam accumulates in the nip between the two piles and the combined material emerges on the other side of the nip in the form of a carded cotton which is cemented by a porous coagulum and penetrated by it. b) A foam similar to that described in Example a is placed in the nip of a pair of rollers provided with a coagulant on one side of a fabric web, e.g. B. a fabric from Indiana. The resulting product consists of the Indiana fabric, which is coated on one side with a thin layer of porous rubber.



   In both cases the coagulant used was 10% aqueous acetic acid; the vulcanization can be carried out in a known manner after drying.



   The dispersions which are used according to the invention in the state of a foam include those which consist of rubber, gutta-percha, balata or similar natural or artificial plant substances in the vulcanized or in the unvulcanized state or
